SENSOR ADjUSTMENT & PROGRAMMING
To program the RW3U600, you use controls
located under the ON/OFF button. The wall
switch cover plate must be removed to gain
access to the mode button and adjustment
trimpots under the ON/OFF button.
For multi-way operation, the
Operating Mode and the Time Delay
adjustments should be the same in all
sensors related to the same load.
1. Firmly grasp the side edges of the
Lock Bar and gently pull it away from
the switch face until it clicks. Do NOT
attempt to pull the Lock Bar off of the
switch!
2. Firmly grasp the side edges of the ON/
OFF button. Slide the button downward
approximately 1/2 inch to expose
the mode button and adjustment
trimpots.
Setting up the Operating Mode
Select the operating mode by pressing the Mode button. The green LED behind
the switch button blinks to indicate the selected mode:
• One blink indicates Mode 1 (Vacancy Sensor Operation), Manual-ON/OFF,
Auto-OFF.
• Two blinks indicates Mode 2 (Occupancy Sensor Operation), Auto-ON/OFF with
manual control and reset to auto (after 5 minutes of vacancy).
To change the operating mode, press the Mode button. The LED blinks to indicate
the selected mode. After that, the unit operates in the indicated mode.
Adjusting the Time Delay
Turn the right trimpot counter-clockwise to reduce the amount of time the lights
will remain on after the last motion detection (minimum = 15 seconds). Turn the
same trimpot clockwise to increase this time delay (maximum = 30 minutes).
You can only select the following values: 15 seconds/5 minutes/15 minutes/
30 minutes.
Warning: Do not overturn the Time Delay adjustment trimpot!
Adjusting the Light Level
This feature is factory set at maximum, so that even the brightest light will not
prevent the sensor from turning the load ON when it detects occupancy. If this
feature is not needed, leave the light level at maximum, fully clockwise.
The light level must be adjusted when lights would normally be turned OFF
because there is enough natural illumination. Each RW3U600 may have a
different light level setting.
1. Set all RW3U600s to Mode 1 (Manual-ON) - except for the one that you’re
adjusting.
Set the RW3U600 you’re adjusting so that it is in Mode 2 (Automatic-ON).
2. Reduce the time delay to 15 seconds.
3. Adjust the Light Level trimpot to minimum (fully counter-clockwise) on the unit
that you’re adjusting. Move out of the coverage area. Let the sensor time out so
lights are OFF and then wait 30 seconds more.
4. Without casting a shadow on the sensor, enter the area. The lights should
remain OFF. Adjust the Light Level trimpot clockwise in small increments.
After each adjustment, wait 5-10 seconds to see if the lights turn ON.
Continue this procedure until the lights turn ON. At this setting the light will
not turn ON automatically with occupancy the if light level measured at this
sensor is above the current natural illumination.
5. Repeat the process (beginning with step 1) for each RW3U600 in your multi-
way configuration until the Light Level has been adjusted properly in all of
them.
6. When you have finished adjusting the Light Level of all the RW3U600s, return
them all to Mode 2.
7. Reset the time delay to the desired setting in all units.
Warning: Do not overturn the Light Level adjustment trimpot!
